With the help of a labelled diagram and Huygen’s wave theory, prove:
When a parallel beam of light is incident obliquely on a plane mirror, angle of reflection is equal to angle of incidence.
Given: Plane wavefront incident obliquely on a plane reflecting mirror surface
To show: Angle of reflection is equal to angle of incidence ($i = r$)
